Mika would seem to be what teachers call an auditory learner. That is, he learns best using his sense of hearing (hey I am surmising here! ) hence he can play music by ear, sing in tune, has a very good ear for languages (and I am a linguist too so I know one when I see one!!); also, his accent changes according to what he is hearing, and I wouldn't be surprised if he is a good mimic/impersonator too.
(go on Mika, do us a Jimmy Saville..... ) And of course he is extremely articulate.
Having said that his visual side would seem to be strong too.
He is endlessly fascinating...............
